Features

High workload rating
Delivering dependable performance to any storage environment, WD Gold hard drives are designed with a workload rating up to 550TB per year, among the highest of any 3.5-inch hard drive.
Enterprise-class storage to rely on
With up to 2.5 million hours MTBF, WD Gold hard drives deliver reliability and durability, are built for yearly operation (24x7x365) within the most demanding storage environments.
HelioSeal Technology
Featured in over 15 million Western Digital hard drives shipped, HelioSeal technology allows for higher capacities and less turbulence on large storage arrays. And now on its 4th generation design, HelioSeal technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust.
Vibration protection
Enhanced RAFF technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus WD's desktop drives in high- vibration environments.
RAID-specific, time-limited error recovery (TLER)
Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Dynamic fly height technology
Each read-write head's fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.
Dual-stage actuator technology
WD Gold drives feature a dual-stage actuator head positioning system for a high degree of accuracy. The primary stage provides course displacement while the secondary stage uses piezoelectric motion to fine tune the head positioning to a higher degree of precision.
Compatibility testing
All WD Gold hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters to ensure ease of integration for a plug and play solution.
